AUGUSTUS MORRIS, OF YOUNGSTONN, NEW YORK.

PLOW-STANDARD.

SPECIFICATION forming part of Letters Patent No. 289,437, dated December 4, 1883. Application filed Jnly26,1883. (No model.)

To all whom it may concern.-

Be it known that I, Aneusrus MORRIS, of Youngstown, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Plow-Standards; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure l is a perspective view of a portion of a plow provided with my improved adj ustable standard. Figs. 2 and 3 are perspective views of the standard and the block or easting, in which the standard slides adjustably, detached and Fig. 4 is a horizontal section on line x 00, Fig. 1.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to plow standards; and it consists in the improved construction and combination of parts of an adjustable standard, as hereinafter more fully described and claimed.

In plowing it is often desirable to raise or lower the body of the plow according to the depth to which the plowing is .done, so as to avoid having the clevis at the front end of the beam too long, and thereby weakening it; and to this end 1 construct a casting, which is secured" to the plow-beam,and in which the standard slides, having a series of notches upon one edge, into which a projection upon a sliding spring-bolt engages, holding the standard in position in its slide. p

In the accompanying drawings, the letter A indicates the plow-beam, upon the central portion of which the slide B is secured, in which slides the standard 0, having a handle, D, at its upper end, by which it may be raised and lowered, as desired. The slide consists of a plate, E, having two inwardly-bent flanges, F, which clamp theedges of the standard, and the centers of which are connected by means of a strip, G, all cast in one piece, which strip connects the edges of the flanges, and furthermore secures the standard in its ways in the slide. At the upper end of the slide is a transverse groove, H, in which slides a spring-bolt, I, the enlarged head J of which projects into a recess or pocket, K, formed by the upper end of one of the flanges, and bears against a spiral spring, L, which forces the head of the bolt out of the recess. The slide is secured to the plow-beam by means of a bolt,which passes through the plate E, through a countersunk perforation, M, in the said plate, the head of the bolt fitting into the countersink, and the bolt passing through the beam, upon the other side of which it is secured bya nut or by similar means. The standard is flat upon one side, which slides upon the plate E, while the other side forms two reduced edges, N, which are clamped by the overturned flanges and a 1ongitudinal web, 0, which fits into and slides in the curve of the transverse strip G. The upper portion of one of the edges forms a rack-bar, P, which is engaged by a rearwardly-projecting tooth, Q, upon the head of the spring-bolt, the head of which projects to the outside to the height of the thickness of the I standard edges, the sliding portion of the bolt sliding under the flat side of the standard, and

the spiral spring in the recess upon the slide forcing the spring-bolt back into the spaces between the teeth of the rack-bar. At the other end the sliding bolt is provided with a turned-up handle or head, which prevents the bolt from being pushed too far in, and offering a flat plate for the person adjusting the plow to placehis finger upon in pressing the bolt in, disengaging the tooth from the rack.

It will thus be seen that the body of the plow may be raised and lowered in a moment of time, changing the depth of the furrow, and by the construction of the standard with its web, and the slide with its transverse strip, and the securing means for the slide to the beam, it will be seen that the severe strain upon the standardand the slide is evenly distributed, making the breaking of the parts of the same more diflicult.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. The combination of the standard, having the longitudinal web upon one side, and means for being adjusted, with the slide having the inwardly-bent flanges, the transverse strip, and means for adjusting the sliding standard, and adapted to be fastened to the beam of a plow by means of a bolt passing through a perbolt, the slide having the inwardly-bent flanges foration in the side of the slide, forming a countersink for the reception of the head of the bolt, as and for the purpose shown and set forth.

2. The combination of a plow-beam having a suitable perforation for the reception of a upon the edges of its sides, the transverse strip passing from one flange to the other, the countersunk bolt-hole for the reception of the bolt, securing it to the beam, the recess formed by the upper end of one of the flanges, and the transverse groove at the upper end, forming a continuation of the recess, the spiral spring bearing with its inner end against the bottom of the recess, the sliding bolt bearing against the end of the spiral spring, and forming at that end a head having a rearwardly-projectupon its .outer end, and the sliding standard having the longitudinal web upon one side,

the handle at its upper end, and forming the rack upon one edge at its upper end, adapted to be engaged b the rearWardly-projecting lug upon the head of the sliding bolt, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

AUGUSTUS MORRIS.
